# Spam Protection

> Add spam protection in front of Formbase.

Formbase does not include built-in spam detection. If you need protection against automated submissions, add it in your frontend or at the edge before forwarding data to Formbase.

Here are the most common patterns.

  <Card title="CAPTCHA" icon="shield">
    Add reCAPTCHA or Turnstile to your form and block submissions when verification fails.
  </Card>

  <Card title="Edge rules" icon="filter">
    Use a reverse proxy or CDN rules to block suspicious traffic or known bot patterns.
  </Card>

  <Card title="Server-side validation" icon="server">
    Post to your own API first, validate the request, then forward to Formbase.
  </Card>

  <Card title="Honeypot fields" icon="bug">
    Add a hidden field and treat filled submissions as spam.

<Callout type="note">
  Combine multiple techniques for the best results. CAPTCHA + rate limiting is a common baseline.
